Summary

The purpose of this guide is to help you install a Tenable Nessus Agent on a Windows operating system and link it to your Tenable Vulnerability Management account. This guide covers the prerequisites, the agent installation process, and configuration of a Nessus Agent scan. Tenable does not recommend using this guide for larger Tenable Nessus Agent deployments, but rather for one-off testing scenarios against a small subset of assets.

Prerequisites

First, you need to download the agent, which is available on our Tenable Downloads site. There are many supported operating systems, but this guide focuses on a Windows installation.

You also need to know how to locate your Tenable Vulnerability Management linking key. You can find your linking key in your Tenable Vulnerability Management account in the Sensors section. For more information, see the Tenable Vulnerability Management User Guide.

Note: Tenable Nessus Agents communicate outbound on port 443 to cloud.tenable.com. Agents update their own plugins and software automatically.
